On a CM-5
The Resources pane provides this data for a CM-5 system:
* PM cpu (user) - This is partition-manager CPU time used by the
program.
* PM cpu (system) - This is partition-manager CPU time used by the operating
system on behalf of the program.
* PM O - This is time spent in /O on the partition manager.
* PM Total is the total of these resources. It represents the program's use of
the partition-manager subsystem.
* Node cpu (user) - This is the time that the program spent in processing
on the nodes. It refers to the amount of time any nodes were active.
* Node cpu (system) - This is node CPU time used by the operating system
on behalf of the program.
* Comm (Send/Get) - This is the time that the program spent in router
communication (sends and gets) on the CM.
* Comm (NEWS) - This is the time that the program spent in NEWS communication
(also referred to as grid communication) on the nodes.
* Comm (Reductions) - This is the time that the program spent doing data
reductions on the nodes.
* Comm (PMNode) - This is the time spent in communication
between the partition manager and the nodes.
* Node I/O - This is the time spent in /O between the nodes and /O
devices.
* Node not profiled - This is the time spent on the nodes by routines that
weren't compiled with the -cmprof ile option. (These include routines
in CM libraries such as CMSSL.) If the routine had been compiled with
-cmprofi le, this time would be allocated to the other node resources.
This resource is available only as of CM Fortran 2.1 and CM-5 C* Version
7.1; for programs using earlier versions of these languages, time spent in
routines not compiled with -cmprofile is not measured
* Node+Comm Total is the total of these resources. It represents the program's
use of the node subsystem.
